Now I don't really know what exactly you are asking but out of all the options I would choose C

The answer is:  [C]:  "Tienes que lavar el auto."  .

Explanation:

Fernando:  {"What more (else) do I have to to do?"}; (translated to English).

Fill in the blank with the correct answer choice.

Answer choice  [A]:  "Leo las leyes de Ecuador".  
 
{"I read/do read/(or, in a sense, "will read")/am reading  the laws of Ecuador"}.   is illogical and incorrect response.

Answer choice [B]: {"Yesterday, I read the laws of the office/building/organization"}.   is illogical and incorrect response.

Answer choice [D]: {"I took out the trash".}   
                     is illogical and incorrect response.

Answer choice: [C]:  "Tienes que lavar el auto". ("You have to wash the car/auto"), is a logical response to:

"¿Qué más tengo que hacer?" {"What more/else do I have to do?"}; 

 and as such, Answer choice: [C] is the correct answer.
